I have a couple of orchids that have developed so many roots that the plants themselves have become pushed out of their pots and are now almost growing sideways.

Toronto Master Gardeners has an excellent section on orchids that will address all of your questions on re-potting and fertilizing. Below is the link for your perusal:
